From low- to high-tech project management

Project management is a complex activity and it involves, among other things, an attitude, style and philosophy. The main proposition of this article suggests that different projects must be approached by different managerial philosophies. The article presents a conceptual managerial classification of projects based on their technological uncertainty — specifically the newness and complexity of the technology involved. It classifies all projects into four types: lowtech, medium tech, high-tech and super high-tech, and then proceeds to describe the major differences among them.
Special attention is then paid to the 'higher' technology types — high-tech and super high-tech projects — and to the attitudes and tools that are needed for managing them. Such projects, if well executed and successful, may help improve competitive advantage and commercial position. They involve however substantial risk and high probability of failure. Several examples of super high-tech projects carried out in the past are described, and their management style discussed in light of the classification presented here. These examples include the SR-71 'Blackbird' aircraft, the 'Apollo' moon-landing program, Data General's 'Eagle' computer and NASA's program of developing the Space Shuttle.

Determinants of the Level of Knowledge Application: A Knowledge‐Based and Information‐Processing Perspective*

Knowledge application is of key importance in the development of successful new products. Knowledge application refers to an organization's timely response to technological change by utilizing the knowledge and technology generated into new products and processes. This study uses the knowledge‐based theory of the firm and considers its roots in the information‐processing approach to organization theory to identify and structure potential antecedents of knowledge application. This study develops four hypotheses concerning antecedents of knowledge application. The hypotheses are tested using data collected from 277 high‐technology firms. Empirical results indicate that a long‐term orientation supported by a research and development (R&D) budget, formal rewards, and information technology directly increases the level of knowledge application, while R&D co‐location indirectly increases the level of knowledge application. It is surprising to find that an increase in the level of organizational redundancy reduces the level of knowledge application. The findings also suggest that information technologies, lead‐user, and supplier networks do not appear to significantly influence organizational redundancy.     

Developing the Teaching of Food Technology in Primary Schools in England through Curriculum Development and Initial Teacher Education

This paper investigates developments in the teaching of food technology introduced as an element of design & technology in the 1990 National Curriculum for Technology in the English primary curriculum for children aged five to eleven years. It reviews briefly the situation for food teaching before 1990 and identifies a number of relevant issues. This is followed by an overview of developments in food technology in primary schools between 1992 and 2001, highlighting the need for primary teachers and trainee teachers on initial teacher education courses to develop an understanding of how to teach food technology in their schools. The development of teaching materials through the Nuffield Approach to food technology in primary schools is outlined together with a case study of the use of the materials in initial teacher education at the University of Surrey Roehampton. The paper describes the uptake of Nuffield Primary food technology materials as measured by down loads from the Nuffield Primary Design & Technology web site. Alongside this, there are reflections of primary trainee teachers on the impact of using the Nuffield food technology materials on their classroom practice during school experience. It concludes with a discussion of the key issues arising from the paper and suggestions for future research. This revised version was published online in July 2006 with corrections to the Cover Date.
